IMPROVEMENT IN PITMEN FOR SAWS.

Specification forming part of Letters Patent No. 51,029, dated November 21, 1865; antedated November 18, 1865.

To all w/Lom it may concern:

Be it known that I, HARRISON C. ELLIN- WOOD, of Garrettsville, Portage county, State of Ohio, havein vented new and usefulImprovements in Pitmen to be attached to Muley-SaWs5 and I do hereby declare the following to be an exact description thereof, reference being had to the accompanying drawings, and to the letters' 0I" reference marked thereon, making a part ot' this specication.

The nature of my invention consists in the arrangement and combination of a double guide, operated by a continuous slide more` ment to operate (as a short pitman) a muleysaw.

The object is to place the saw near to the driving-wheel by a short gearing to prevent the trembling motion of the saw and give it a more regular operation, producinga smoother and Inore even sawing,

Figure 1 represents a tront View; Fig 2, a side View.

A represents the frame to which the guiderods B and driving-Wheel O are attached.

The traveling frame D, which takes the place of an ordinarywrist and pitman, is perm anently fastened to the guides B. This frame has an opening7 E, through its center with grooved edges, in which the continuous slide G operates. The slide G is attached to the driving-heel by a bolt through the center of the slide, the slide being of an oblong shape with grooved ends corresponding with the grooves at the sides ofthe frame D at the opening E. The short gearing or rod H is permanently attached to the front of the frame D, and operates in an iron post, l, as its guide. A muley-saw isintended to be attached to the end of this rod H, which gears the saw closer to the driving wheel than as usual to the ordinary pitmen and Wrist.

TheguidesB are iron rods extending beyond its square frame D, and operate in the ends of iron posts J.

K is the crank to which the engine is to be geared.

I do not claim a frame with a slideoperating initonadriving-Wheelfordrivingamuley-saw; but

What I claim as my invention, and desire to secure by Letters Patents, is

The arrangement and combination of the double guide-rods J with their frame, D, slide E, and rod H, operating as a short pitman, as herein described, and for the purposes set forth.
